In this short math video we will answer a standardized math test question by identifying a mapping diagram that is NOT a function. We will review that a function maps each input to exactly one output. We will review each answer choice...

In this short video we will answer a standardized math question where we are given a table of a linear relationship and asked to find the value of y given a value of x. We will identify the constant rate of change and extend the pattern...

This video explains how to determine if a relation is a function using mapping diagrams, tables, and the vertical line test. The lesson covers the concepts of inputs and outputs, ordered pairs, and the definition of a function as a...

This video lesson teaches/reviews how to write a linear function from a real world graph in slope-intercept form. Topics that will be covered include - finding slope from a graph, finding slope from two points, finding the y-intercept...
